Question: Regarding Purchasing a Subscription for the New York Public Library

I would like to put copies of the International Socialist Review in the New York Public Library. As a start, I'd like to put them in the NYPL branch libraries in Washington Heights and Inwood.

I am willing to pay the NYPL for the ISR subscriptions, at least for these 2 libraries. In the future, I'd love to see more ISR's in the New York City regional library system, but this is where I wish to start.

As librarians, what do you recommend as the best way to do this? Obviously I can approach a librarian at the branch, but I wonder if you can suggest an approach or talking points to use that would promote the likelihood of my getting the library to sign on.

I realize this is not strictly a reference question, but I value your advice and appreciate any suggestions.
